Ok I lied, someone put together a nice summary from reddit:
I'm making this list here for a few reasons... Reddit makes people's sites crash and I'm hoping you guys read this instead of giving incgamers more traffic since they leaked the information out early (which is a pretty ****ty thing to do for those of us who play by the rules - very unprofessional IMO).
Anyway, here's the main details I took from the event:
We weren't given a beta start date. Beta does look to be coming soon though - I'd expect an announcement at the investor conference call on August 3 by Mike Morhaim. My guess is sometime this month.
The game doesn't look overly "ready" at this point. I will be surprised if they hit a 2011 release date.
The game is online only. No offline characters (I'm expecting this to be rather controversial in the community)
2 different kinds of auction houses will be in the game.
1 auction house is virtual money for items. So you'll be able to trade for items with in game currency.
The other auction house is to use real currency. This is player to player transaction (NOT Blizzard selling items - they made this very clear at the event). There is an unknown to us at this time 3rd party that Blizzard will be working with. They will be taking a cut in the sales. Blizzard is doing this because they realized the market was there in Diablo and Diablo 2 and the scamming that went with it. In this way they can control it (and what they didn't tell us but is obvious, capitalize on it).
Beta will have all 5 classes and will be able to play through the campaign through King Leoric. Basically the same thing we mostly saw at events like Blizzcon.
There will be a shared stash between your characters on your account.
There will be a hardcore mode. Same as Diablo 2. You will not be able to use the real currency auction house in hardcore mode.
They have completely trashed the talent tree system and have replaced it with runes.
It doesn't appear there will be a console release of the game when it goes live. Mac and PC will come out at the same time (duh). Not to say they won't release on a console in the future but it won't be with the initial release.
There's more information I'll be adding soon (running out of time and need to make sure our articles publish at 12:01) - so I'll be adding more here. Feel free to add some more in this threads comments on some of the big stuff I may have missed... but so far the ones I mentioned were the biggest that were up for discussion at the event on Wednesday.
If anyone wants - we host/own http://blizzplanet.com - we make literally nothing off the website (in fact we lose hundreds every year to pay for hosting, airline tickets and hotel rooms for events, etc.). It's a labor of love to us and we've been doing this for 10 years now. There's more info posted there with more in depth FAQs, screen shots, videos, etc.
EDIT: Here's our link with all the FAQs and the B-roll video: http://www.blizzplanet.com/blog/comm...event-coverage
EDIT 2: added info about trashing the talent tree system.
From reading the IGN stuff there will be a console version of the game eventually.
